CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 323,951, dated August11, 1885.

Application filed December 3, 1884. (No model.)

To all whom it may concern,.-

Be it known that I, WILLIAM H. NEWLON, a citizen of the United States,residing at Beaver Falls, in the county of Beaver and State ofPennsylvania, have invented certain new and useful Improvements inGar-(louplings, and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters and figuresof reference marked thereon, which form a part of this specification.

My invention relates to automatic carcoup- 1ers which are adapted towork in connection with ordinary couplers when required, the object ofthe invention being to furnish a stron g and reliable automaticcoupling, which cannot be accidentally uncoupled and which may be usedto connect with cars provided with ordinary couplings and of variousheights.

In the accompanying drawings, Figure l isV a perspective view of acoupler constructed according Vto my invention. Fig. 2 is a sideeleva-tion of two of such couplers coupled together. Fig. 3 is aperspective view of a coupler of niodiiied construction. Fig. 4 is aside elevation of two of such modied couplers coupled together. Fig. 5is a side elevation of a coupler of my construction coupled with anordinary car-coupler. Fig. Gis a bottom view of a car illustrating themanner of attaching the couplings thereto.

Referring to Fig. I, the letter A indicates the draw-bar, on the frontend of which is an upwardly-,projecting hook, B, the front surface ofwhich is a straight rearward and upward bevel.

At each side of the drawbar, at the base of the hookvB, are lateralextensions G (l, partly for the purpose of giving the draw-bar anextended bumping-head and partly for the purpose of supporting thecoupling-loop D in proper position for automatically engaging withanother coupler.

To the rear portion of the draw-bar a pin, E, is secured by a chain andis intended to be inserted in an oblique hole, f, in the draw-bar, asshown in Fig. 2, to prevent the couplingloop from becoming disengagedfrom the hook.

The loop D is pivoted on a level With the base of the hook, the draw-barat a point in the rear of the hook being somewhat thickened, as shown atg, in order to afford a rm hold for the pivot-pin h.

The draw-bars may be connected in any ordinary manner to the cars, but Iprefer to connect them in a manner which will be presently explained.

In using the couplers to couple two cars together the loop on one carwill be laid back, as shown in Fig. 2, and the loop on the other carwill be allowed to rest on the lateral exf tensions C C ot' thedraw-head, these extensions supporting the loop in proper position forits front end to strike the inclined surface of the hook on the othercar and ride up over and fall behind such hook when the two cars arebrought together. After the loop has be come engaged with the hook thepin E is inserted in the oblique socket formed to receive it, and willobviously prevent the loop from becoming disengaged from the hook. Thispin must, of course,be removed in uncoupling the cars, and as both itsinsertion and removal from its socket are performed after the cars cometogether there is no danger attending its manipulation.

In the modiiied form of my coupling, as shown in Fig. 3, I dispense withthe lateral extensions C C of the draw-head and form a horizontalpassage through which the pin'E may be inserted at the base of the hook,said pin, when being thus inserted, serving to support the loop inproper position for engagement with another coupler. In this form of thecoupler, a chain for attaching the pin E to the draw-bar is alsodispensed with, as said'pin will always occupy either the horizontalpassage at the base of the hook or the oblique socket behind said hook.When these modified couplers are used for coupling two cars together,the loop of one coupler will be laid back, as shown in Fig. 4, and theloop of the coupler which is to engage therewith will be supported bythe pin E in its horizontal socket. Vhen the cars have been coupled, thepin E will be taken from its horizontal socket in the drawbar which hasits hook engaged with theV opposite loop and will be inserted in theoblique socket'behind said hook IOO to prevent the engaged loop frombecoming disengaged therefrom by the jolting of the cars.

In Fig. 5 the letter J indicates an ordinary car-coupler, supposed to beattached to a car at a less height than are the couplers of myconstruction to other cars. In such case a bent coupling-link, K,will beused, in order that its projecting end may strike the inclined frontsurface of the hook of a coupler of my construction on another car andglide over the same to become engaged therewith. The pin E is used toprevent disengagement of this link the same as with a loop, as beforedescribed.

I have stated that the draw-bars may be connected with the car in anywell known manner; but I prefer to connect them as shown in Fig. 6. Inthis ligure it will be observed that two draw-bars, A A, at oppositeends ofthe car, are connected by an adjustable rod., R, passing underthe car and provided with collars fr, between which and the crosstimbers or sills t ofthe car are stout springs S. These springs preventto a great extent the jarring and strain incident heretofore to thestarting and stopping of a train.

It will be readily seen that my improved coupler is adapted to work inconnection with any of the ordinary old-style linleeouplings, so thatthere will be no inconvenience from shifting cars to dilterent roadsafter they have been provided with my improved coupling.

Having now described my invention, and explained themode ofusingthesame, I claiml. In a car-coupler, the draw-bar A, having at itsfront end the rearwardly and upwardly inclined hook, and the lateralextensions G (l at the base ot' said hook, in combination with thecoupling-loop pivoted to the draw-bar in the rear of said hook andarranged to be supported by said lateral extensions7 substantially asdescribi d.

2. In a car-coupler7 the draw-bar A, pro vided at its front end with therearwardlyinclined hook, and lateral projections from the front end ofthe bar for supporting a couplingloop, in combination with thecoupling-loop pivoted behind the hook, and the pin having' an obliquesocket provided for it behind the hook, substantially as described7 andfor the purpose set forth.

In testimonyT whereof I affix my signature in presence of two witnesses.
